NSLogger is a remote logging framework for Apple (iOS, macOS, tvOS) and Android platforms. It consists of client libraries (C/Objective-C Swift wrapper for Apple, Java for Android) that send structured log messages (text, binary data, images) over TCP to a desktop viewer application. The desktop viewer (macOS app) provides real-time log viewing with filtering, color coding, search, marks, export, and preference management. An iPad viewer application also exists for on-device log viewing with Core Data persistence and Bluetooth support. The codebase includes multiple Xcode projects for different targets, test apps, and vendored third-party libraries (BWToolkit, HockeySDK-Mac, SSSelectableToolbar). While functional and well-known (4.9k stars), the project shows significant age: manual memory management (non-ARC), duplicated viewer logic across Desktop and iPad, incomplete features (JSON message format stubbed), outdated dependencies, and deprecated API usage. It remains a valuable reference for implementing a custom binary logging protocol and network transport layer, but would require modernization for current platform versions.
